I've been using constant contact for a number of years for my email newsletters. It's very good for the data it supplies on the behaviour of my subscribers. One of its useful features is that it allows you to send customers emails or newsletters automatically when they sign up and you can schedule as many as 10 emails (effectively an autoresponder).
This is great for me as each person who signs up receives 10 emails which have been particularly designed for new subscribers over a period of 10 months. The problem I have is that constant contact only allows one autoresponder for all my different subscribed lists. What I need is an autoresponder email tool like constant contact that will allow people to sign up to my different lists and receive 10 different automatic emails depending on what they've signed up for e.g. those that sign up for special offers receive my best 10 special offers, those that sign up for newsletters receive 10 of my best newsletters etc.
Anyone have any ideas on a tool/software/product you've used that may do this? Ideally I still want the tool to have the useful data on open rates, click rates etc.
